AKANTIOR contains the active substance polihexanide.
AKANTIOR is used in adults and children from 12 years of age to treat Acanthamoeba keratitis, Acanthamoeba is a parasite (tiny organism that lives inside humans and can cause disease) which can cause an infection resulting in keratitis (inflammation of the cornea, the clear layer in front of the eye). Acanthamoeba keratitis can cause severe defects on the surface of the cornea, including ulcers (open sores).
AKANTIOR damages the membrane (outer skin) of the Acanthamoeba parasite resulting in leakage of the cellular contents which destroys the cell. AKANTIOR also prevents the Acanthamoeba parasite from making copies of its DNA by interfering with enzymes (proteins) responsible for the replication process, which stops the growth and reproduction of the parasite in humans.
Talk to your doctor or pharmacist before using AKANTIOR.
Treatment with AKANTIOR may cause you mild to moderate eye discomfort (such as eye pain) and eye redness. In the case you are experiencing a severe eye reaction, contact your doctor.
There is no experience of using AKANTIOR in pregnant women. AKANTIOR is not recommended during pregnancy. If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
It is unknown whether AKANTIOR passes into breast-milk. Ask your doctor or pharmacist for advice before AKANTIOR treatment.
This medicine contains approximately 0.4 mg phosphates in each drop which is equivalent to 11 mg/mL. If you suffer from severe damage to the clear layer at the front of the eye (the cornea), phosphates may cause in very rare cases cloudy patches on the cornea due to calcium build-up during treatment.
Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.
The treatment consists of two parts: intensive treatment that lasts for the first 19 days and continuation treatment that lasts from day 20. The recommended dose is 1 drop of AKANTIOR in the affected eye as follows:
Starting intensive treatment (19 days)
Apply one drop every hour (16 times a day), for the first five days (days 1 to 5)
Apply one drop every 2 hours (8 times a day), for a further seven days (days 6 to 12)
Apply one drop every 3 hours (6 times a day), for a further seven days (days 13 to 19)
Continuation treatment
Apply one drop every 4 hours (4 times a day), until there is no corneal inflammation or no evidence of infection (cured) Your doctor will advise you when to stop treatment.
Use AKANTIOR as prescribed for best effect. Always tell your doctor if you are thinking about stopping the treatment.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
